To all whom t'm'aby 'concer-: l I i 'Be it'known'that LTHoMAs W. BROWN, a cltizen of the United States,

Falls, in the countyfof Hardin-and State `of 5 Iowa, have invented a certain new and use# 'ful Shocker Attachment for Binders, of

y which the following is a specification.

' The objects of my invention are to provide a shocker attachment for `harvesters of sim.

:o ple, durable,` and inexpensive construction Which can b'e easily and readily attachedv to the harvesters already inuse and which is adapted to bind several bundles together and when the bundles' are,A tied together and a shock is formed to allow lthe shock to be dropped onto the ground-surface in astandingpos'ition.4 i

' A further Vobject `which ,a certain predetermined number of bundles may be bound together as the harlve'ster'is operated 'and yet to avoid the necessity of binding eachgseparate bundle tothe 'other bundles, and thus lessen the labor in the operation of the bundles when taking the stackdown'. v A further object is to provide an auxiliary needle attachment, for shocking which [is Vmounted on anextension of the shaft upon which the binder-needle is mounted vand the 3o ordinary knotter attachmentsjdcsigned to coact with the auxiliary needle in knotting the binding material'when acertain prede-v vtermined number of bundles have been bound by the binding-needle.

My invention consists in certain details .in

the construction, arrangement, 'and combination of the various parts of vthe-'device whereby the objects contemplated are. attained, as hereinafter more fullyA set forth, pointed out in my claims, and illustrated in the .accompanying drawings, in .which-`- Fi ure. l is a plan view of the delivery side l of a binder, showing the ordinary binder attachinent Aand m shocking attachment. Fig;4 2 is a sectionalyview of the delivery side lof vabinder, showing 'the way in which the bundles are held together in constructing the shock and my sho'cker-needle and other at` tachments.

Fig. 6- is a detail view of the binderec'am.

Referringto the accompanying drawings,

I. have used the reference-.numeral 10 to in'- dicate ,the platform over which the grain to 6o be' bound passes as it is fed ,to position where itis bound.

The reference numeral 11 indicates the .1

frame which extends from the body of the Iharvester underneath the side delivery mech- 6 5 anism. `It is upon this frame 11 that the ene tire binder and shocker attachment is mounted. Mounted on the frame 11 is a substantially U shaped frame having'the circular lowerportion12, the upper portion 13, and 7o the connecting-piece 14 therein. The connecting-piece 14' vextends through the platform 10, and the lower portion 12 is mounted beneath-the platform 10 and the portion'l above said portion 12. Extending longitudinally of the portion 12'- beneath and transversely ofthe platform 10 is the needle-shaft 15, having the .crank 16 at its forward end.v Keyed to the:

needle-shaft15 is the binding-needle 17 Vand 8e the shocker-needle. 18, each of'which is made in the vordinary way and is shown fully in Fig.' 1 of the drawings. Extending longitudinally '.of the upperportion .13 of the U- shaped frame is 'the knotter-shaft 19., having 85 the bevel-'gear 20 on its forward end. This bevel-gear is in mesh. with. the bevel-gear 2 1, which 1s operatively connected withthe main driving-shaft 2 2 by means ofthe shaft 23 and .the bevelgears 24 and 25, so that'as the main 9o driving-shaft is Aoperated the bevel-gear 20 will be correspondingly operated. There is a bearing 26 extending forwardly from `the bevel-gear 20, andashaft 27- connects the bearing. 26 with the crank 16 on the needleo5 shaft 15, lso that whenthe shaft 19 is driven` the needle-shaft 15 will be rocked so as to op'- erate the needles mounted thereon and force said needles upwardly and partially around thev grain to be bound andinto the knotters roc which are connected with the upper portion' 13 of the U-shaped frame. f

'Connected with the knotter-shaft 19 and adjacent to .the free end of the upper portion '13 yof' the U-s'hapedlframe is the ordinaryy 1o5 vknotter mechanism of the binder. Rotatably mounted at the rear of theordinary knotter mechanism on the binder-shaft 19 is the cam-.wheel 28, having the gearl29 on a 'portion of its periphery. The cam 28, withits 11o platform 10 and outside of the 75 gear 29, is designed to operate the knotter and the knife for severing the binding material after it has been knotted. A more complete description of the knotter and the knife for cutting the binding material is deemed unnecessary, owing to the fact that these parts are duplicates of the ordinary binding mechanism. have provided a notch 3() in the periphery of the gear 29, into which the mechanism for retaining the cam against movementJ is forced except when it is thrown into operation by releasing said mechanism. Extending rearwardly from the cam 28 is the ratchet-faced projection 31. This ratchet-- faced projection encircles the shaft 19.

Slidingly mounted ,on the shaft 19 and at the rear of the ratchet-faced projection 31 is the ratchet-faced collar 32, having the annular groove 33 encircling it. Encircling the rear end of the shaft 19 is the sleeve 34, which is connected with the uard-frame 35 and assists in supporting the free end of said guard -frame Extending upwardly from the sleeve 34 are the lugs 36. Slidingly -mounted in these lugs 36 and extending longitudinally above the shaft 19 is the mechanism for throwing the shoeker-knotter out of or into operation. This comprises the bar 37, which has the projection 38 extending at right angles to it, upon which the roller 39 is mounted, the purpose of which is hereinafter made. clear. This sliding bar has a downwardly-extending member 40, which enters the groove 33 in the collar 32, so that as the sliding member 37 is moved forwardly and rearwardly the ratchet-faced collar will be forced into or out of engagement with the ratchet-faced projection 31. Connected with the forward end of the sliding member 37 is the cam-engaging member 42, having the downwardly-extending projection 43 at its forward end, which is designed to enter the notch 3() in said camand hold the cam in position avainst rotary movement vwhen the ratcl'iet-faced collar 32 is out of engagement with the ratchet-faced projection 31. There is a spring 44 mounted on that portion of the sliding member 37 which is between the lugs 36, designed to Anormally force the sliding member forwardly and so that the ratchetfaced collar 32 will be normally forced forwardly and into engagement with the ratchetfaced projection 31 except when the sliding member is held at its rearward limit of movement against the resistance of the spring 44. Mounted on the extreme rear end ofthe knotter-shaft 19 a gear 45, which is in mesh With the gear 4G, which is mounted on the stub-shaft 47 at the rear of the binder-shaft. This gear 46 is so mounted that 'the roller 39 on the sliding member 37 will he normally iu engagement with its rear face. On the rear face of the gear 46 is a curved projection 48, against which the roller is designed to rest during part of the movement of said gear and 6 5 while the shock is being formed. When the roller is in engagement with the curved projection 48, the sliding bar is thrown to its rearward limit of movement, and the projection 43 is in the notch 30, the ratchet-faced collar 32 is out of engagement with the ratchet-faced projection 31, and the cam 28, which operates the knetter and knife, is maintained in position against rotary movement. As soon as the roller 39 passes out of engagement with the circular projection 48 it drops against the rear face of the gearwheel 46, and the spring 44 causes the lug 43 to be thrown out of engagement with the cam 28 and the ratchet-faced collar 32 to be forced into engagement with the ratchetfaced projection 31, and as the shaft 19 continues its rotation the knetter and knife will be operated by the cam 28 when the shocker-needle reaches its proper position. As soon as the roller 39 again engages the projection 48 'the parts will take the relative positions above described and the cam for operating the shocker-knotter and knife will be maintained out of operation. until the next shock is formed. It will be seen that in operation both the binder-needle f17 and the shocker-needle 18 will be rocked at every revolution of the shaft 19 and that if the ordinary binder-knetter 'is used in connection with the binder-needle 17 the knetter and cutter will operate with each operation of the binder-needle 17l` but that although the shocker-needle operates with each rocking of theneedle-shaft 18 and revolution of the knotter-shaft 19; the shocker-knetter and cutter will not operate in conjunction with the shocker-needle 18 except when the ratchetfaced collar 32 is in engagement with the ratchet-faced projection 31, and as these parts are in engagement with each other only when the roller 39 is out of engagement with the circular projection 48 the knot-ter will 'only operate after a certain number of bundleshave been formed and only when a predetermined number of bundles have been bound by the binder-needle. inasmuch as the twine or other binding material is attached to the binder in the ordinary Way a further description of this is deemed unnecessary. Suffice it to say that the twine extends from its point of attachment in the binder through the needies 17 and 18 in the ordinary way and extends to the twine-box 49.

Pivot/ally mounted at the extreme outer side of the frame 11 is the rock-shaft 50, to which the shmak-supporting yrods 51 are pivotally attached-and capable of movement, as shown in Fig. 5. These supporting-rods 51 are held firmly against rotary movement on the shaft 50, but they are capable of slight pivotal movement, so'that their lower ends swing longitudinally of the shaft as the shaft IOO lIO

is rocked. u There is a guide-4l bar 52 through i the curved slots53,

supporting position.

in which the shock-sup porting rods .51y pass. These slots 53 act as guides for the rods'51 rocked-that is, whenA the rock-'shaft 50 is rocked in one direction'the outer ends of the rods 51 will --be swung downwardly and rearwardly, and when said shaft 50 is rocked in the opposite .direction the rods 51v will'be drawn to their upperlimit of movement-that is, moved forwardly and upwardly to their Firmly attached to the forward end of the rock-shaft 5 0 is the arm 54,'having the operatingrod 55 pivotally attached to it, .This rod 55. is held in position by any mechanism suitable to maintain it against longitudinal movement and to release it from its locked Yposition when desired, When the rod 55 is at its inner limit ,of movement and locked in that position, the

shockesupporting rods 51 will beat their upper limit of lmovement,`so that the bundles of grain can be fed down upon them and they will support these bundles.

ever, a shock has been formed limit of movement, the weight ofthe shock will cause the supporting-rods 51 to bemoved to their -rearward lowerlimit of movement, and thus the shock will be allowed to fall upon the ground andas it falls be so'turned that when it reaches the ground it will bein a standing. position, said shock being turned-- by the direction of the rods 51 when they are in their lower rearward limit of movement, together with the assistance'of the stationary rod 56,` which extends outwardly from and at right angles to the rear end of the plate 52,

`in sucha way that the upper portion of the i rotatingit slightly."

In f ractical operation the i. bundles l are forced one at a time after being bound by the binder against the twine and when the 'pre-L determined number of bundles havevbeen movedA toward the shock supporting rods the shocker-knotteris enabled to cooperate wi th the shocker-needle in v ing material around the shock, and-then the -knotter mechanism vis thrown out of o era,
